Simple deep vein catheterization set

Abstract

The invention relates to the technical field of deep venipuncture, in particular to a simple deep vein catheterization set. The simple deep vein catheterization set comprises a catheter body, whereina plurality of catheter side hole joints are regularly arranged on the outer side surface of the rear end of the catheter body; a syringe body is arranged on the outer side of the catheter body; and alaser oxygen saturation testing instrument is arranged on the outside of the syringe body. By arrangement of the syringe body with a long needle head, the needle head of the syringe serves as a guidewire, the needle head and the catheter body are inserted in a vein of a patient together favorably, meanwhile, by the laser oxygen saturation testing instrument which is arranged on the syringe body,blood which enters the syringe body is measured and distinguished to judge whether the catheter enters the artery of the patient or not, meanwhile, a catheter tail end rubber plug is arranged at thetail end of the catheter body, after the needle head is pulled out, the catheter is sealed automatically by the rubber plug, the simple deep vein catheterization set is simple and convenient to operate, the circumstance that the catheter enters the artery mistakenly can be avoided, the problems of breakage and dropping of a guide wire due to a traditional seldinger technology and possible significant complications are avoided effectively.

Description

technical field [0001] The invention relates to the technical field of deep vein puncture, in particular to a simple deep vein catheterization set. Background technique [0002] Deep vein puncture and indwelling catheter is one of the commonly used operating techniques in intensive care. It is the most effective way to monitor central venous pressure, infusion, blood transfusion, hemodialysis and complete parenteral nutrition in patients with critical illness, major surgery and chronic wasting disease one. The indwelling catheter for deep venous puncture can protect the patient's peripheral veins, prevent irreparable damage to the veins caused by infusion of irritating drugs and hyperosmolar or viscous drugs, reduce the pain of repeated peripheral venous puncture infusions, and has safety The advantages of convenience and simple maintenance. [0003] The procedure of traditional deep vein puncture indwelling catheter is to use a puncture needle with a needle core to penetr...
